back to serious note; i remember there was a fighter from germany who came to our club to train for a few months. one tournament we went together, she put on her shiai gi, and she wanted to warm up with me, and i literally could not get a grip on her. the collar was so thick and stiff, it actually hurt my wrist to trying to get a proper grip on it. and the back too. the back of the gi was so stiff, it wouldn't fold in order for me to get a grip on her back.
did she win her matches on the merit of her gi? no. she had good judo. but, if two equally talented people stepped on the tatami, one should not walk away the victor simply because of the tayloring of the gi either. (she did lose the finals though. she went for a belt grip throw on the opponent and got countered for ippon.)
your gear matters. it really is no different than that tired discussion on gi vs. no-gi.

p.s. Don't tell us you're a girl too, there aren't any on the Internet.

Many things we do naturally become difficult only when we try to make them intellectual subjects. It is possible to know so much about a subject that you become totally ignorant.

Anyone who bitches about a gi effecting their game is a bitch. Plain and simple. I wear my stiff double weave bad ass competition gi in practice. The collar is so think you can't even choke me with it as it won't wrap around my neck.

That doesn't stop my betters from beating the **** out of me. And their flimsy single weave doesn't give me any noticeable advantage. I'm still laying flat on my back trying to figure out how it all went wrong.

If a gi is the difference between winning and losing, maybe you need to look at your training a bit more.
